We couldn't resist talking about this lovely knitted robots by Jess Hutchison. After all, that's a geek girl right there.
All the robots on display at her site are knitted with wool and require no batteries to run. Okay, they don't run you need to move them around by hand.
Too bad, she hasn't any for sale currently. But, if you are interested drop her a mail. Here's the link to her site.
